摘要:

当输入空间由标量变量组成时,神经网络在回归和分类问题上表现出色。由于这种熟练程度,已经开发了几个流行的软件包,允许用户轻松地适应这些类型的模型。然而,该方法排除了函数协变量的使用,到目前为止,还没有软件允许用户使用这种广义输入空间构建深度学习模型。据我们所知,函数式神经网络(FuncNN)库是任何编程语言中的第一个这样的包;该库是为R开发的,构建在keras架构之上。在本文中,介绍了几个函数,为用户提供了一个轻松构建模型,生成预测和运行交叉验证的途径。报告还概述了基本方法。最终的贡献是一个包,提供了一套通用的建模和诊断工具的数据问题,其中存在功能和标量协变量。

英文摘要:

Neural networks have excelled at regression and classification problems when the input space consists of scalar variables. As a result of this proficiency, several popular packages have been developed that allow users to easily fit these kinds of models. However, the methodology has excluded the use of functional covariates and to date, there exists no software that allows users to build deep learning models with this generalized input space. To the best of our knowledge, the functional neural network (FuncNN) library is the first such package in any programming language; the library has been developed for R and is built on top of the keras architecture. Throughout this paper, several functions are introduced that provide users an avenue to easily build models, generate predictions, and run cross-validations. A summary of the underlying methodology is also presented. The ultimate contribution is a package that provides a set of general modelling and diagnostic tools for data problems in which there exist both functional and scalar covariates.
